Description

Step deep small hole measuring tool

Technical Field

The utility model relates to a measuring tool technical field especially relates to a step depth aperture measuring tool.

Background

Conventionally, a common depth gauge cannot be used for probing measurement due to the small aperture of a step deep hole, a rear extension rod of a vernier caliper is used for measuring the depth, and the hole depth is deep, so that the operation is inconvenient and the measurement error is large.

SUMMERY OF THE UTILITY MODEL

Therefore, the utility model provides a measuring tool of the degree of depth of accurate measurement step deep hole.

Further, the height of the first standard block is equal to the height of the second standard block.

Further, still include the measurement sighting rod, the diameter of measurement sighting rod with the aperture phase-match of through-hole, the outer wall of measuring the sighting rod has scale value.

Further, the first standard block, the second standard block and the measuring marker post are all made of stainless steel.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise. Furthermore, the terms "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The embodiment of the utility model provides a step deep hole measuring tool, as shown in fig. 1-3, include: the first standard block 1 is matched with the aperture of the large hole 31 of the step deep small hole 3 to be detected, and the second standard block 2 is matched with the aperture of the small hole 32 of the step deep small hole 3 to be detected; the first standard block 1 is detachably connected in the large hole 31, the first standard block 1 is provided with a through hole 11 matched with the second standard block 2, and the second standard block 2 is detachably connected in the small hole 32 and the through hole 11. The utility model discloses first standard block 1 and second standard block 2 are respectively in the step deep hole's that awaits measuring macropore 31 and aperture 32 phase-match, with first standard block 1 insert behind the macropore 31, insert the aperture 32 with second standard block 2 through the through-hole again to will be difficult to go deep into measuring aperture 32 degree of depth lifting and come out, conveniently accurately measure the degree of depth of aperture 32.

As shown in fig. 3, in order to make the depth a of the raised hole consistent with the depth a of the original hole, the height of the first standard block 1 is equal to the height of the second standard block 2.

It should be noted that, when the number of steps of the step-depth small hole is greater than 2, the small hole 32 corresponds to one of the step-depth small holes to be measured, and the large hole 31 corresponds to the largest step-depth small hole of the step-depth small holes. Therefore, the technical scheme of the application is suitable for measuring the depth of any small hole with a plurality of stepped deep small holes.

The embodiment of the utility model provides an aspect, still include the measurement sighting rod, the diameter of measuring the sighting rod with the aperture phase-match of through-hole 11, the outer wall of measuring the sighting rod has the scale interval. The measuring marker post can be inserted into the lifted small hole, so that the depth of the small hole can be conveniently measured. Preferably, the first standard block 1, the second standard block 2 and the measuring marker post are made of stainless steel, so that the effects of preventing corrosion and guaranteeing the measuring precision are achieved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
